PMG Service

PMGs have a very long useful life, but they do need periodic maintenance as voltage can degrade over time. Our Factory Repair and Training Center in Wisconsin offers a full range of services for both Woodward and Pelton units, including:

Overhaul

Disassemble, clean and inspect

Upper and lower bearing replacement

Test and verify PMG output voltage

Test and verify Speed Switch settings

Remagnetization

Stator Lead Repairs

Auxiliary Speed Switches

These switches run at a multiple of turbine speed and require more frequent overhaul. In addition to offering overhaul parts for field replacement, we also offer reconditioned speed switches and factory speed switch overhauls. Each overhauled speed switch will be tested and adjusted on our speed switch test stand to match your specified trip settings.
